Abstract

SHANGASE, M. O; ISHWARKUMAR, S  and  PILLAY, P. Morphology and Morphometry of the Hyoid Bone in a Black South African Population. Int. J. Morphol. [online]. 2021, vol.39, n.1, pp.134-137. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022021000100134.

The hyoid is a unique, ‘U’ shaped bone, located on the anterior aspect of the neck, between the mandible and thyroid cartilage. This bone displays morphological and morphometric characteristics that can assist in determination of age, sex and race of an individual.Therefore, the present study aimed to investigate the morphology and morphometric parameters of the hyoid bone in a Black South African population of KwaZulu-Natal. The morphological and morphometric parameters of the 40 hyoid bones obtained from the Department of Clinical Anatomy, University of KwaZulu-Natal were classified in accordance with Deepak et al. (2013). In this s. tudy, 35 % of hyoid bones were ‘U’- shaped and 65 % were ‘V’- shaped in males, whereas in the female specimens, 70 % of hyoid bones were ‘U’- shaped and 30 % ‘V’- shaped. Furthermore, this study recorded a statistically significant relationship between the shape of the hyoid bone and sex. With regard to the morphometry, the width of the hyoid bone was greater in males than females however; the length of the hyoid bone was greater in females than males. In addition, this study concludes that these results may contribute to the existing knowledge on the morphology and morphometry of the hyoid bone and may assist forensic procedures.
